Do not publish numbers that cannot be checked against a source page.
Methodology
How the calculators are built
Every page is based on published source material, explicit exclusions, and review dates that make it easier to judge what the estimate does and does not cover.
Rules
Base rules for every calculator
Prefer official pricing pages and explicit provider documentation over inferred values.
Mark missing or uncertain data rather than pretending it is exact.
Common exclusions
What most calculations leave out on purpose
Storage, egress, taxes, and reserved discounts are excluded unless a provider publishes them clearly and comparably.
Per-GPU equivalents are labelled when a provider only publishes pricing for a multi-GPU node.
Only pages with live source links and visible review dates are kept in the public site.
